I was wondering if the same cams are used from each of these companies is the quality of a big bore kit the same from companies like fuel moto, hillside,tman Gmr, Head quarters ,or is one better than the other or are they pretty much the same

 

It would come down to the quality of the bore job, honing, ring fitting, etc, and the quality of the piston used in each kit. All of these things can help or screw up the finished product.

 

I've never used any of the above listed but I would suggest call each and get a feel for how they sound and who sounds the most helpful. Also do a search and see what people are saying about each of these venders. Fuel moto is getting alot of talk about the 107 and the price is Great.

Just my 2 cents

 

I can only speak on the quality of HQs products, having had a 103. 107 and currently having a 107--their quality is outstanding; I stick with what I know; I have dropped at least 10k with them over the past three years and really got my $$$ out of each build.

 

I guess I'm still undecided which company to use. They all seem like they advertise good services so it'll be a coin toss to decide.

 

Some companies bore out stock cylinders for a 107, some companies like (RevPerformance) have a set of larger cylinders for the 107, so there is more wall left. I'm pretty sure T-man uses the revolution cylinders, Fuel Moto bores out stock ones, not sure what HQ does, (I want to buy from American companies, but more importantly I want to buy from a company that I can call and talk to a person if I have to, HQ only cooresponds via E-mail from what I hear, and their not US based).
